Description 

Heavy duty, high power changeover relay rated at 12V, 70A.  Commonly used in starter motor and other higher current applications.

Features a diode fitted across the coil (terminals 85 & 86) to suppress voltage spikes that occur in the coil circuit when the relay is de-energised. If not suppressed these can damage sensitive circuit components such as those found in central locking or alarm systems.

Important: +12V must be applied to terminal 86 and ground to terminal 85. If this is reversed the diode may be damaged.

Note: This relay has three 9.5mm wide terminals (30, 87 87a) and so will not fit any of our relay sockets.

Sold individually.

I bought two of these to operate a two speed cooling fan. They were fitted over the winter but have now been actually used for real in hot conditions in southern Europe. One has failed. In my view this item has two problems. Firstly, despite being rated for 70 amps it appears to have exactly the same internals as the 40 amp relay, including very small make/break contacts. Secondly, the main power input connector is located in the housing in a very mechanically weak manner which, in my case, failed to resist the effort required to push on a tight terminal. This resulted in the terminal wobbling in the case which, as it is a single pressing incorporating the contract, made its function erratic. If you buy one of these treat it very gently and, given its contact sizes, don't expect it to withstand heavy use.
